Fulcrum of Fate Harry Potter/Bill Weasley Fed up with the responsibilities heaped upon him after he defeated Voldemort, Harry flees the UK in search of his yet unknown soulmate.
A few years later, when Charlie receives an urgent owl from Bill, asking for his discretion and his help, he never expected to find his adventurous older brother living in domestic bliss. How the two have been able to keep everyone from finding out so long, Charlie does not know.
He is also unaware that soulmates are, in fact, real. Though he is about to find out the truth for himself - in a very, very, unexpected way. Even by wizarding standards. Ao3 link: https://archiveofourown.org/works/22713889
